I have two examples which will say that we will do what we want to do and we will believe in what we want to believe and we will consume what we want to consume even if it is harmful to us .
Cigarette smoking is injurious to health and drinking alcohol is injurious to health. They are written on the labels of the products, harmful effects of consuming them are proven in many scientific and medical journals, they are not allowed to be advertised in media, all doctors strictly asks patients to stop smoking and drinking. Yet many people continue to do so at their own peril.
